CISA warns of surge in cyberattacks on U.S. water systems after Minnesota breach

CISA warns of a rising trend of hackers targeting U.S. water and wastewater facilities by manipulating PLCs and changing passwords to lock operators, prompting boil-water notices and manual operation. Minnesota reported a coordinated attack affecting more than 30 community water systems earlier this week, with investigators briefly weighing a possible Iran link; the overall water infrastructure remains vulnerable as probes continue.
